It's a great short-series for children that lets you explore all these everyday situations together with the girls. It's also just super cute to see them hanging out at the cafe while the older operators watch over them. Each episode has its own theme and it's always surprising how much can be packed into 3 minutes. The hand-drawn animations are simple but at the same time very beautiful and full of character.
Having some basic knowledge about Arknights is very helpful to understand the references, but it's not necessary. (The metal crabs belong to Beanstalk, the owner of the cafe. It's an alternate scenario where the characters get to live normal lives at the base, the Rhodes Island landship, instead of joining battles as operators)
If I had kids who were able to read subtitles I would force them to watch it.
